RP Data is expanding its presence in the New Zealand property research market. The company announced yesterday that it will increase its shareholding in PropertyIQ from 50 per cent to 60 per cent, after reaching agreement with PropertyIQ's other major shareholder, Quotable Value. RP Data is a wholly owned subsidiary of CoreLogic, which claims to be the world's largest property data and analytics provider. Potential bidders for the foreign exchange company, OzForex, include private equity firms Bain Capital, Permira and Silver Lake, as well as the trade buyer Travelex, according to the Australian Financial Review. Macquarie Group, OzForex's largest shareholder, is looking to make an exit and is hoping to caitalise on its strong growth in recent times. A case brought by a former Bankwest customer, which is scheduled to start on Monday, will raise issues relating to Commonwealth Bank's controversial handling of Bankwest's loan portfolio after it acquired the bank. The Australian reports that the case is being brought by Scott Michaelson, who was involved with International Skin Care Suppliers and CPL Australasia. Details of the claim were not reported.
